Gladiolus and lily are two of the most popular bulb crops in Taiwan flower
industry. Plant health management has been developed well suited for their production.
Under the priority of sustainable development, these standard processes for either
bulb or cut flower production are very important to entrepreneurs interested in global
operation of agriculture business. This is a good model for sustainable agriculture
development based on environment protection and operation profit

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Seeds and seedlings are the basic in agricultural production. Good flower’s
product must be come from healthy seedling. Seed quality, medium, environmental
condition and field management are major influence factor for healthy seedling. Good
seed quality will also be included maximum genetic purity, maximum seed viability
and specific pathogen free. When seeds harvests must be dried, screened and stored in
short time for postponing seed life. Breaking dormancy (e.g. growth regulator of
gibberellin) and priming treatment before sowing will be increased the rate of seed
germination and uniformity. Plug tray system by means of mechanization and
save-labor culture, save-time culture is gradually taking over the traditional seedling
growing pattern. The optimum condition of water, temperature, oxygen and light…
etc., will be beneficial for seed germination and seedling growth. Medium kinds
should be considered is also very important factor. Using specific secretion of
microorganism, e.g. Trichoderma spp., Giocladium spp. or chemical compound, e.g.
salic acid, phosphorous acid could induce plant defence system, by means of
phytoalexin production to resist pathogens invasion and to enhance plant defence
function. This article was investigated about influence factors(such as seed production,
harvest, drying, storage and nursery culture…etc.) of seed quality and seedling health
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
